unbuild an array

[AFLAMENT]

Hi,
I would like to know how to unbuild an array, a reverse process of "build array" ?
If it's not possible, how to create a VI with a selectable input/output number.
As "build array", in which you can choose number of input/output by sliding "build array" icone.

Thanks

"Index array" and "Array subset" functions.

I recommend you to do some tutorials in LabVIEW, this is a far too basic question.

edit:  you can also use a FOR loop with autoindexing to get elements from an array. All depends on your actual task during coding...

Here you can find some learning material:

Spend 1 minute to look in the Array palette.  Look at the context help for each of the functions.  You will find more than you were looking for.  But this is a very basic thing that you could have figured out just by digging into the palettes.

Hi,

Please, before treating people as newbies, try to understand the question..

That what I want to do; Thanks

And Index Array is not doing that for you?

We did understand the question.  Use Index Array and take some tutorials.

Good, I forget that index array give output witout any value on index inputs.

So, what about the second part of my question?

..how to create a VI/function with a selectable input/output number.
As "build array", in which you can choose number of input/output by sliding "build array" icone.

(that what is really interest me to know?)

Thanks

Index Array does't do that?  I thought I clearly showed that is how it works.

If you are asking how to create a subVI that has a variable number of array inputs, you can't because the connector pane can't be modified in run-time (unless maybe with VI scripting?).  You just make your input a 2-D array and index that inside the subVI.

A 2D array needs to be rectangular.  If the 1D input arrays can have different lengths, an array of cluster of array might be better.
